West Ham have reportedly added Valentin Castellanos to their shortlist of transfer targets. The Lazio forward is rumoured to be attracting attention ahead of the next transfer window, with insiders claiming preliminary talks could soon take place. Talks are underway, and with no competition emerging, West Ham are seen as the sole contenders for the player's signature. In season 25/26, West Ham are only scoring 0.86 goals per game (6 in 7), below the Premier League average. Valentin Castellanos would be brought in to give them more bite in the final third. West Ham have recently been linked with Adama Traore, Endrick Felipe Moreira de Sousa and Joshua Zirkzee while Lazio have had no rumoured targets. Stay tuned for more details as the story develops.
